Hi Denis,
If I understand you well you will wait with pulling the airbrakes until the
glider has stopped its rotation and then carefully put some back pressure on
the stick. I was considering the idea of pulling the brakes with the glider
still in its rotation mode in order to keep forward speed as low as possible
at any time. However this may frustrate the spin recovery action; I just
don't know. What's your idea about this. Of course handbooks do not say
anything about this.
the ASH 26 handbook does say "spinning is not noticeably affected by
extending the airbrakes paddles, but it will increase the height loss
when pulling out, and is therefore less advisable"
I suppose the last sentence refers to loss of total energy (i.e. after
recovery you will re-gain more height if you made it without airbrakes
than with). It is not true of height loss down to lowest point (you will
loose less height with airbrakes because the diving speed is diminished
and the curving radius is reduced by the square of the speed -- even
with 3.5 G allowed w/ airbrakes instead of 4 G w/o the height loss
should be lesser with airbrakes out --
